JOHN W. RHOADES, OF HOLDREGE, NEBRASKA.

WINDOW AND noon scnnniv.

Application filed February 5, 1915.

To all whom it may concern Be it known that 1, JOHN W. RHoADns, a citizen of the United States, residing at I-loldrege, in the county of Phelps and State of Nebraska, have invented certain new and useful Improvements in WVindow and Door Screens; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window or door screens, and one of the principal objects of the invention is to provide means for permitting flies to escape from a room through properly formed openings in the frame of the screen leading from the inside to the outer atmosphere, and means being provided whereby the flies cannot reenter through the openings.

It is a well known fact that flies when they light upon a window screen climb up the screen to the top and if they can find an opening to the outer atmosphere they will enter this opening and eventually find themselves on the outside of the window.

Taking advantage of this fact, the present invention has for its principal object the formation of certain exit openings for flies which are flaring at their entrance point within the room and gradually converge to a comparatively small exit opening outside, thus providing means for leading flies out through the frame of the screen.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which Figure 1 is a view in elevation looking at the screen on the inside of the room. Fig. 2 is an enlarged detail section taken on the line 22 of Fig. 1, and Fig. 3 is a view in elevation of the top portion of the screen frame during the process of manufacture.

Referring to the drawings, the numeral 1 designates a screen frame, which may or may not be provided with a cross bar 2 at the center thereof. The screen material 3 is connected to the frame in any suitable manner.

Connected to the top bar 4 and extending transversely across is a substantially triangular shaped strip 5 in cross section, said strip being inclined on theline 6 as shown in Fig. 2, and secured to the bar 4: by any suitable means. This strip 5 is provided Specification of Letters Patent.

with a pair of spaced inverted V-shaped recesses 8. Connected to the strip 5 is the substantially triangular strip 9, having a smooth inner face and secured by any suitable fastening means designated at 7 and 10. By securing the-strip 9 to the strip 5, flarlng exit openings 11 are formed in the upper portion of the window frame, which converge from their lower edge 12, to a point 13, and from this point to the upper edge of the frame, the openings are provided with parallel or vertical sides 14. To finish the screen frame, the upper edge of the screen material 3 is secured to the inner inclined smooth face of the member 9, thereby forming the openings on the interior of the screen frame.

From the foregoing it will be obvious that the inclined openings 11 leading from the interior of the room to the outside will entice flies to crawl up the screen and out through the flaring openings. The screen can be manufactured at a cost but slightly greater than the ordinary window screen, and the provision of means for the escape of flies renders it a much more efficient and desirable device than the ordinary screen structure.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined in the claims.

What is claimed is 1. A screen frame having connected to its upper cross bar, a triangular strip provided with a pair of inverted V-shaped openings, a second strip having the upper edge of the screen material secured to its inclined face, and secured to the first named strip, providing fly exits therebetween.

2. A screen frame having connected to the upper cross bar a substantially triangular strip, said strip provided with a pair of spaced inverted V-shaped openings converging at their lower edges to a point adjacent their upper edges and the walls extending outwardly and vertically, forming openings, a second strip secured to said first mentioned strip and carrying the body of the screen material on its inclined face providing the openings between the two members, said openings flaring at their inner entrance points and contracted at their exit points on the outside of the building at the top of the frame.

3. A Window screen frame having a triangular strip secured transversely across the tWo strips and together being inclined from top bar, said triangular strip provided with a pair of inverted V-shaped recesses converging at their lower ends and contracted at their upper edges, a second strip having the screen material secured to its inclined face secured to thefirst mentioned strip, said openings being formed by connecting the the 1nner side to the upper side thereof. 10

In testimony whereof I afiix my signature in presence of two witnesses.
